Answer:
x >.2
Step-by-step explanation:
3x + 2.4 > 3
Subtract 2.4 from each side
3x + 2.4-2.4 > 3-2.4
3x > .6
Divide each side by 3
3x/3 > .6/3
x >.2
Answer:
Step-by-step explanation:
13=12
14=15
15=8
16=17
<h2>Divide the entire thing by 3</h2>
<h2>You can find the roots by using the quadratic formula or by using the form x²-Sx+P</h2>
<h2>Two numbers whose sum is -5 and product is -6</h2><h2>-6 and +1</h2>
<h2>Your answer is B</h2>
X + 65 = 120
-65 -65
x = 55
Answer:
there is significant evidence to support that the claim that the mean time women spend watching television less than the mean time spent by men.
Step-by-step explanation:
H0 : μw = μm
H1: μw < μm
The test statistic :
(x1 - x2) / sqrt[(sp²/n1 + sp²/n2)]
df1 = 14 - 1 = 13
df2 = 17 - 1 = 16
Pooled variance = Sp² = (df1*s1² + df2*s2²) ÷ (n1 + n2 - 2)
Sp² = ((13*4^2) + (16*4.2^2)) ÷ (13 + 16)
Sp² = 16.90
t = (12.9 - 16.4) ÷ sqrt((16.90/14 + 16.90/17))
t = - 3.5 ÷ 1.4836645
t = - 2.359
Using the Pvalue from Tscore ; at 95% ; df = 29
Pvalue = 0.0126
Pvalue < α
0.0126 < 0.05 ;
Hence, we reject the null and conclude that there is significant evidence to support that the claim that the mean time women spend watching television less than the mean time spent by men.
